Implementations

impl LibError

pub fn strerror(&self) -> Result<&'static str>

Get the string description of a LibError, using the btrfs_util_strerror() function provided by libbtrfsutil.

LibError provides an std::fmt::Display implementation provided by thiserror. This function should not be the preferred mechanism for obtaining the error message.

Trait Implementations

impl Clone for LibError

fn clone(&self) -> LibError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LibError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for LibError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for LibError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for LibError

fn eq(&self, other: &LibError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<u32> for LibError

type Error = LibError

The type returned in the event of a conversion error.

fn try_from(errno: u32) -> Result<Self>

Performs the conversion.

impl Eq for LibError

impl StructuralPartialEq for LibError
